I am not so optimistic. I worry that many of the people dying from COVID in Red states are the left-leaning minority. Remember, a mask does not protect its own wearer, but instead protects the other people in the room. So if rightists do not wear masks while leftists do, leftists will get infected by rightists more frequently than the other way round, since in effect the leftists are protecting the rightists but the rightists are not reciprocating.
(This is why I have said that it should be legal to shoot on sight anyone not wearing a mask.)
